How to convert amounts of money, USD currency, to US American English words, as dollars and cents written with letters

How to convert amounts of money, without decimals, to US American English words?

To write an integer number we first must know the place value of each digit.

For example, the number 1,234,567 has a 1 in the millions place, a 2 in the hundred thousands, a 3 in the ten thousands place, a 4 in the thousands place, a 5 in the hundreds place, a 6 in the tens place, and a 7 in the ones place.

So, 1,234,567$ = one million two hundred thirty-four thousand five hundred sixty-seven dollars.

Notes:

2: Placement of word "and": in American English do not use the word "and" after "hundred", "thousand" or "million". So, it is "one million two hundred thirty-four thousand five hundred sixty-seven" and not "one million and two hundred thirty-four thousand and five hundred and sixty-seven", though you may hear a lot of people using the last form, informally. On the contrary, the "and" word is always used in British English.
